A man today went on trial accused of sexually assaulting and murdering his teenage sister.

Connor Gibson allegedly killed Amber Gibson, 16, at Cadzow Glen in Hamilton on November 26 2021.

Prosecutors at the High Court in Glasgow claim the 20-year-old removed Amber's clothes and repeatedly inflicted blunt force trauma to her head and body.

Gibson - who also uses the name Niven like his sister did - is then said to have strangled the teenager with his hands.

It is claimed he did this with intent to rape Amber and did murder her.

Gibson faces further charges of attempting to defeat the ends of justice and attempting to pervert the course of justice.

This includes claims he got rid of clothes he had been wearing and that he called the children's home Amber was staying at to pretend she was still alive.

Gibson is also said to have told police he last seen his sister after she walked off from an argument near to a community centre in Hamilton on the day of the alleged killing with him then allegedly visiting another man in the town.

Stephen Corrigan, 45, is a co-accused of Gibson.

He does not face the murder allegation, but is instead charged with breach of the peace and attempting to defeat the ends of justice.

It is claimed Corrigan found Amber's body, but rather than alert police, he inappropriately touched her and then hid her remains under bushes and branches.

This is said to have occurred on an occasion between November 26 and 28 2021.

Corrigan has lodged a special defence of alibi that he was elsewhere at the time.

Gibson - represented by Tony Graham KC - and Corrigan - whose lawyer is solicitor advocate Rhonda Anderson - both deny the charges.

Richard Goddard KC is leading the prosecution.

Addressing jurors at the start of the trial, Lord Mulholland told them verdicts should be returned on the evidence and not based on “emotion”, “morality” or “lifestyle” choices of others.

The trial continues.
